I wanted a way to make it easy to figure out which version of a language
server Zed is running. Now, you get a tooltip when hovering on a
language server in the Language Servers popover.

/>

This PR also fixes a bug. We had existing code to open a tooltip on
these language server entrees and display the language server message,
which was never fully wired up for `CustomEntry`s. Now, in this PR, we
will show show either version, message, or both, in the documentation
aside, depending on what the server has given us.

Mostly done with Droid (using GPT-5.2), with manual review and multiple
follow ups to guide it into using existing patterns in the codebase,
when it did something abnormal.

Release Notes:

- Added language server version in a tooltip on language server hover

how many days ago that thread was had in. Hovering over the thread item
shows you both the title and the full date, if needed (time and date).

We can first review to ensure this change meets both `Zed` and user
requirements, as well as code rules. Currently, we only support
user-level settings. We can wait for this PR:
https://github.com/zed-industries/zed/pull/43173 to be merged, then
modify it to support both user and project levels.

When profiling Zed with Instruments, a warning appears indicating that
surfaces cannot be pushed directly to the display as they are
non-opaque. This happens because the metal layer is currently marked as
non-opaque by default, even though the window itself is not transparent.

<img width="590" height="55" alt="image"
src="https://github.com/user-attachments/assets/2647733e-c75b-4aec-aa19-e8b2ffd6194b"
/>

Metal on macOS can bypass compositing and present frames directly to the
display when several conditions are met. One of those conditions is that
the backing layer must be declared opaque. Apple’s documentation notes
that marking layers as opaque allows the system to avoid unnecessary
compositing work, reducing GPU load and improving frame pacing

Ref:
https://developer.apple.com/documentation/metal/managing-your-game-window-for-metal-in-macos

This PR updates the Metal renderer to mark the layer as opaque whenever
the window does not use transparency. This makes Zed eligible for
macOS’s direct-to-display optimization in scenarios where the system can
apply it.

Release Notes:

- gpui: Mark metal layers opaque for non-transparent windows to allow
direct-to-display when supported

Closes #ISSUE

Removes a few eager container clones and iterations.

Added a todo to `get_prev_tab_group_window` and
`get_next_tab_group_window`. They seem to use `HashMap::keys()` for
choosing the previous tab group, however `.keys()` returns an arbitrary
order, so I'm not sure if previous actually means anything here. Conrad
seems to have worked on this part previously, maybe he has some
insights. That can possibly be a follow-up PR, but I'd be willing to
work on it here as well since the other changes are so simple.

Closes #ISSUE

A [modal dialog](https://en.wikipedia.org/wiki/Modal_window) window is a
window that demands the user's immediate attention and blocks
interaction with other parts of the application until it's closed.

- On Windows this is done by disabling the parent window when the dialog
window is created and re-enabling the parent window when closed.
- On Wayland this is done using the
[`XdgDialog`](https://wayland.app/protocols/xdg-dialog-v1) protocol,
which hints to the compositor that the dialog should be modal. While
compositors like GNOME and KDE block parent interaction automatically,
the XDG specification does not guarantee this behavior, compositors may
deliver events to the parent window unfiltered. Since the specification
explicitly requires clients to implement event filtering logic
themselves, this PR implements client-side blocking in GPUI to ensure
consistent modal behavior across all Wayland compositors, including
those like Hyprland that don't block parent interaction.
- On X11 this is done by enabling the application window property
[`_NET_WM_STATE_MODAL`](https://specifications.freedesktop.org/wm/latest/ar01s05.html#id-1.6.8)
state.

I'm unable to implement this on MacOS as I lack the experience and the
hardware to test it. If anyone is interested on implementing this let me
know.

## Summary
Fix panic "cannot update workspace::pane::Pane while it is already being
updated" when dragging terminal tabs to split the pane.

## Problem
When dragging a terminal tab to create a split, the app panics due to
re-entrancy: the drop handler calls `terminal_panel.center.split()`
synchronously, which invokes `mark_positions()` that tries to update all
panes in the group. When the pane being updated is part of the terminal
panel's center group, this causes a re-entrancy panic.

## Solution
Defer the split operation using `cx.spawn_in()`, similar to how
`move_item` was already deferred in the same handler. This ensures the
split (and subsequent `mark_positions()` call) runs after the current
pane update completes.

## Test plan
- Open terminal panel
- Create a terminal tab
- Drag the terminal tab to split the pane
- Verify no panic occurs and split works correctly

- Follow up to https://github.com/zed-industries/zed/pull/45097 — not
showing raw inputs for edit and terminal calls
- Removing the display of empty Markdown if the model outputs it

Closes #44717

Sometimes, we show the user the agent's auth methods because we got an
AuthRequired error.

However, there are also several ways a user can choose to re-enter the
authentication flow even though they are still logged in.

This has caused some confusion with several users, where after logging
in, they type /login again to see if anything changed, and they saw an
"Authentication Required" warning.

So, I made a distinction in the UI if we go to this flow from a concrete
error, or if not, made the language less error-like to help avoid
confusion.

Release Notes:

- Fixed an issue on windows where clicking buttons on windows in the
background would not register as being clicked on that window

They count the requested max_output_tokens against the prompt total.
Seems like a bug on their end as most other providers don't do this, but
now we just default to None for the main models and let the API use its
default behavior which works just fine.

- deepseek: Fix issue with Deepseek API that was causing the token limit
to be reached sooner than necessary

Closes #45179

## Summary

Fixes the focus behavior when creating terminals with
`RevealStrategy::NoFocus` or `RevealStrategy::Never`. Previously,
terminals would still receive focus if the terminal pane already had
focus, contradicting the documented behavior.

## Changes

- **`add_terminal_task()`**: Changed focus logic to only focus when
`RevealStrategy::Always`
- **`add_terminal_shell()`**: Same fix

The fix changes:
```rust
// Before
let focus = pane.has_focus(window, cx)
    || matches!(reveal_strategy, RevealStrategy::Always);

// After  
let focus = matches!(reveal_strategy, RevealStrategy::Always);
```

## Impact

This affects:
- Vim users running `:!command` (uses `NoFocus`)
- Debugger terminal spawning (uses `NoFocus`)
- Any programmatic terminal creation requesting background behavior

Release Notes:

- Fixed terminal focus behavior to respect `RevealStrategy::NoFocus` and
`RevealStrategy::Never` settings when the terminal pane already has
focus.

Release Notes:

- Allow using locally installed `ty` for Python

**Root Cause**:
Empty local workspaces returned `DetachFromSession` from 
`serialize_workspace_location()`, and the `DetachFromSession` handler
only cleared the session_id **without saving window bounds**.

**Fix Applied**:
Modified the `DetachFromSession` handler to save window bounds via
`set_window_open_status()`:
```rust
WorkspaceLocation::DetachFromSession => {
    let window_bounds = SerializedWindowBounds(window.window_bounds());
    let display = window.display(cx).and_then(|d| d.uuid().ok());
    window.spawn(cx, async move |_| {
        persistence::DB
            .set_window_open_status(database_id, window_bounds, display.unwrap_or_default())
            .await.log_err();
        persistence::DB.set_session_id(database_id, None).await.log_err();
    })
}
```

Previously, when opening a new project (one that was never opened
before), the window bounds restoration logic would fall through to
GPUI's default window sizing instead of using the last known window
bounds.

This change consolidates the window bounds restoration logic so that
both empty workspaces and new projects use the stored default window
bounds, making the behavior consistent: any new window will use the last
resized window's size and position.

Closes #45092 

Release Notes:

- Fixed new files and projects opening with default window size instead
of the last used window size.

Initial implementation in ce884443f1c38ca8da9edf9fbbb8e7fd579452cb used
`Arc` to store the reference to the hash map inside the iterator while
keeping the lifetime static. The code was later simplified in
5151b22e2ea37fb457cf4f88b88fe4f315306074 to build the list eagerly but
the Arc was forgotten, although it became unnecessary.
